Judgments for inaccessible targets: comparing recognition without identification and the feeling of knowing

Abstract:
Both the recognition-without-identification (RWI) and feeling-of-knowing (FOK) paradigms attempt to tap participants' sense about a target that is inaccessible. In the case of RWI, participants judge the likelihood that the inaccessible target was studied. In the case of FOKs, participants judge the likelihood that the inaccessible target will be recognized at a later point in time. The present study compared the two using a hybrid paradigm. The patterns of responding differed depending on whether the judgment was of the RWI type or the FOK type. For the former, ratings were significantly higher for studied than for unstudied inaccessible targets (the typical RWI effect). For the latter, ratings were significantly lower for studied than for unstudied inaccessible targets (a reversal of the usual RWI effect). Similarity of the targets and distractors diminished the usual RWI effect, but not its reversal in the FOK situation, suggesting that the bases of the two effects differ. A potential explanation is that when participants judge whether an inaccessible target was presented earlier, they are oriented toward relying on cue familiarity, which should be greater for cues of studied targets, whereas when they judge whether they will recognize an inaccessible target later on, they are oriented toward relying on the accessibility of information, which is greater in the unstudied condition, due to the lack of priming of the targets.

Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
